Application tiled February 14, 1908. Serial No. 415,917.

To all whom 'it concem' Be it known that I, THoiiiAs S'. PATTERSON,

a subject of the-King of Great Britain and Ireland,` residing in Rosemont, Pennsylvania, have invented certain Improvements in Washing-Machines, of which the following `is a specification.

My invention relates to certain improvements in machines for washing loose material and removing the water from the material after washing.

My invention is particular] adapted for ilse in connection with was ing material lmownas waste or rags, from which the oil has been previously removed and which i must be thoroughly cleansed vand washed before it canbe used again.

Waste and rags are used particularly in railway car axle boxes, and in machine shops and manufacturing establishments in general, and it is now the practice instead ol discarding the oily waste to remove the oil from the waste and wash the waste so that it can be used again.

The object ofV my invention is to provide a single machine which will thoroughly wash the waste or like material, and in which the water used in washing can be quickly removed froni the material without allowing the scum to renter the material when the -tlie construction in which a filter is used.

A is a casing inclosing the chamber A in which .the cage B is mounted.

C is a vertical shaft mounted in a bearing.

A2 is a frame secured to the central portion of the casing A, as clearly shown in Fig. 1, and containing a stepped bearing a at the bottom, and a bearing a near the top. The steppedbearing a in the present instance is a ball bearing consisting of two disks a2 with balls a3 between them. Other forms of bearings may be used without departing from my invention.

T he cage B consists of a base portion B having a central portion b and a screen b having at its upper end an internal flangev b, and on the base portion B is a series of blales b forming the wheel of a turbine mo or.

E is a nozzle projectin through the caspipe E has a valve e and the pipe F is a bypass connected to the pipe E on each side of the valve e and has a valve f and a reducer f', preferably of the form shown in Fig` 5.

he reducer consists of two parts f2, fs of a. couplingl between which is mounted a disk f* havin a small hole therein. Other forms of .re ucer may be used if desired. T he opening in the disk ft can be of any diameter according to the amount of steam re uired to wire-draw through the redur. en it is desired to turn the cage slowly the valve e is closed and the valve f is opened, allowing the steam to pass uthrough the pipe F and wire-draw through the reducer f', but when it is desired to turn the cave rapidly the valve e is opened and the va ve f closed, allowing steam at full pressure to pass through the nozzle.

In the bottom of the cage B is a series of openings i in which are mounted valve casings I inclosing ball valves i adapted to seats in the casing and held in place b a cross bar 2, or other suitable means, `as c early shown in Fig. 4. These valves may be placed any distance apart as desired, but they should be centered in respect to the center of rotation of the cage; and there may be two or more series of the valves spaced any distance apart, depending upon the size of the apparatus.

Mounted in the cage is a projecting nozzle g in line with the openings z in the cage, and this nozzle is attached to a steam supEly pipe G provided with a valve g, so t at when steam is turned into the Iipe G' a jet of steam will be forced throng the nozzle and through the openings z' in the cage, entering the cage and agitating the material under treatment.

The casing A inclosing the washing chainb'er A is, during the washing process, `filled with water so as to submerge the material in the cage during the washing process. h is Mounted upon vthe'cage is a detachable' screen N carried by a spider-71, confined to the cage by a set screw n adapted to the threaded end of the shaft C. This screen is preferably madeflexible and extends under the internal flange of the cage, and is for the purpose of holding materlal within the ca e below the surface of the water.l

Other orms of screens may be used without departing from my inventlon.

A3 is a cap for the casing, which is held down by a set screw Z9 carrled by a pivoted v arm P inthe present instance.

In order to 4prevent the water rotating with the cage I preferably provide a series of vertical blades `s,s which project into the vwashing chamber from the casing A, and'I also provide a'series of blades s projecting from the bottom-of the casing, for thesame purpose. A

In Fig. 6, I have shown'a modification in which a filter is used to filter the wash water as it escapes, if it is desired soto do. lt'is, a'

wire screen placed against the perforated surface'of the cage and supported by the screen are one or more sheets of ilterin material t; a screen t? of wlre gauze 1s place against the filtering-material so as to keep the waste from coming inv direct'contact withit. s

The operation of the machine is as folvlows When it is desired to Wash Waste, for instancewhich is delivered in small bunches,

- it is preferable to keep the 'waste separated as much as possible, otherwise it has a tend-v ency to cakefand'it is diicult to separate after the treatment. The washing chamber is filled with water in the first instance and small bunches of waste are placed in the cage until the cage is, say, half filled with waste, theuthe valve 'f is opened so as to allow a jet of steam to play through the nozzlc E, and as this steam 1s vWire-drawn only a comparatively smallamount of steamv is by centrifugal force.

projected 4against the blades -of the turbine wheel, and the cage is rotated very slowlyjust sufficient to keep the material under treatment in motion without causing the material to be projectedagainst thescreen b The water is prevented from turnin -with the cage by the fixed blades s, s. Sgteam is then introduced through the pipe G and nozzle g, and is projected through the valved openings in the bottom of the cage, the valves preventing the jet o f steam striking the material with such force as to tear it asundenfbut the steam is spread by the valve and the tendency 1ste open up the bunches of materialand allow the water to gain access to the dirt or other foreign material in the waste.

' After the machineJ is run a given length of time the scum Will rise to the surface, and this is drawn oli' through the outlet pipe k,

and when it is found that the waste is clean and that all the scum has been removed from the surface of the water, thenthe water'is discharged through the outlet' m, the val vel f is closed, the valve e is opened and the-valve (jis closed so that the cage is rotated aty a.

high speed, causing the material within the cage to be forced` outward by centrifugal force and against the screen b of the cage ;Y the water being forced from the material through.the openings will pass away from the machine through the outlet m. After the water isremoved from; the waste the machine is stopped, the 'screen N removed, the contents of the cage taken out, and the cage is'then charged with another batch of material. v

If it is desired to lter the water or other cleansing medium, I place-filtering material in the cage, as illustrated in Fig. 6, and it will be understood that while my invention is especially adapted for use with water,

other cleansing liquids may be used without departing from my invention; i

I claim A 1. -Thel combinationy in a washing machine, of a casing forming a washing chamber, a removable cover for the said chamber, a cagek pivotally mounted in the chamber and capable of receiving the masses of loose material to be washed, said cage having in its bottoln a series of openings, means Afor rotating the cage, and a steam nozzle at the -bottom of the chamber, the opening in the nozzle being in a direct line with the series of o.penings in the bottom of the cage so that.

a )et of steam will be projected into the cage directly through'the openings in succession so as to agitate the material Within the cage by initial force of the jet of steam.

2. The combination of a casing-inclosing a washing chamber, a cage mounted in the washing chamber and "having a series of valved openings, means for turning the cage, and a steam nozzle alining with the openings of the cage so as to deliver st'eamQintothey interior of said cage.

3. The combination of a casinginclosing` a washing chamber, a cage mounted in the chamber, means for rotating the cage, saidI Vcage having av serles of openings in the bottom, valvesvin Said openings, a steam nozzle'mountedunder'the cage and in line with the openin s, whereby as the cage is rotated steam will e projected through the valved openings and into the body of the cage.

4. The combination of ,a casing inclosing 4a washing chamber, a cage mounted in said chamber, means for rotating the cage, there being a series of openings in the bottom of the cage concentric with the center of rotation, a series of ball valves in said openings,

projected from the nozzle as the cage rotates.

5. The combination of a casing, a cage vmounted within the casing, a turbine wheel connectedto or forming part of the cage, a nozzle, two steam pipes connecting with the Y. nozzle, and a reducer mounted in one of the ,j-steampipes sor.4 that when steam is-turned intoone pipe the cage will be rotated slowly and when turned into the other pipe the cage will be rapidly rotated.

6. The combination of a casing, a vertical shaft mounted in bearin s in the casing, a

cage mounted on the s aft and inclosed' within the chamber formed by the casing, means. for closing the casing, means for driving lthe cage, there being a series of valved openings in the bottom of the cage andarranged concentrically with the center of rotation, a steam nozzle projecting under the cage and in line with the valved opening?, a screen closing the upper portion of t e cage, a water inlet, anoutlet communicating with the casing above the upper end of the cage, a water outlet communicating with the bottom of the' casing, and means for preventin the water turnmg with the ca e.

7. 'Iie combination of a casing inc osing a washing chamber, a rotating cage mounted within the casing, a screen and tering material mounted at the periphery of the casing, there being a series of openings in the bottom of the cage, a fixed steam nozzle in line with said openings and arranged to project steam through the openings into the cage, an inlet, and an outlet for Wash water communicating with the casing.

In testimony whereof, Iy have signed my name to this specification, in the presence of two subscribing witnesses.
